ABSTRACT:
A piezoelectric oscillator containing load capacitances utilizing the thickness shear vibration mode of a piezoelectric plate. In this piezoelectric oscillator, a pair of divided electrodes are formed on one major surface of a piezoelectric plate and are divided by a gap provided in a direction extending from one end surface to the other end surface of the piezoelectric plate, and the pair of divided electrodes are formed so as to be opposed to a common electrode formed on the other major surface of the piezoelectric plate through the piezoelectric plate.
